1. Mr and Mrs Burdesha are planning to start a family. However, Mr Burdesha is concerned that, as his brother was diagnosed with Colour blindness, he may be a carrier. Their GP explains how Mr Burdesha may carry the faulty gene for colour blindness using a Punnett square. Using Cc to represent a carrier, create a Punnett square using the template below to explain to Mr Burdesha his chances of inheriting the gene from his parents if both of them were carriers of colour blindness. Explain your answer in terms of gamete formation and fertilisation:
